RE: [PHP] Effects of changing sessid information within URL

> Will changing the sessid information within the URL have any affect on > the REAL session id (initially created when the user logged in)??? No. The file containing the data for the original session will still be there and will be removed when garbage cleanup comes around. If the session id is changed in the URL, that now becomes the user's session id the next time session_start() is called. If a file matching that number is found, then data from that file is loaded. This would be called session hijacking. The idea is, though, that the session id is significantly large enough that by changing it, you're not likely to come across any other session id that's in use. ---John W. Holmes...
